LCD (liquid crystal display)
LCD stands for “liquid crystal display.” It is a type of flat-panel display technology that uses liquid crystals to produce images. LCDs are widely used in electronic devices such as TVs, computer monitors, smartphones, and digital cameras, as well as in many industrial and medical applications. LCDs are known for their energy efficiency, thin profile, and ability to display vibrant colors and clear images. They are often referred to as the “eyeballs” of electronic devices, as they are the main component that allows us to see what’s happening on screen.
LCDs work by sandwiching a layer of liquid crystals between two layers of glass or plastic. The liquid crystals are in a twisted nematic (TN) state and by applying an electrical current, the crystals untwist and allow light to pass through. By selectively turning certain crystals on and off, an image can be formed. LCDs also often use a backlight to illuminate the liquid crystals, allowing for better visibility in different lighting conditions.
One of the major advantages of LCDs over other display technologies is their ability to be made very thin and lightweight. This makes them ideal for use in portable devices such as smartphones and laptops. Additionally, LCDs use less power than other types of displays, such as CRTs, which makes them more energy-efficient.
However, one of the main disadvantages of LCDs is that they can suffer from a phenomenon known as “ghosting,” which occurs when fast-moving images leave a trail behind them. This can be especially noticeable in video games and other fast-paced content. Another disadvantage is that they can have a limited viewing angle, meaning that the image can become distorted if viewed from an angle that is not directly in front of the screen.
Overall, LCDs have become an essential technology in the modern world, and their popularity is only expected to grow in the future.
LED TV’S (light-emitting diode)
LED TVs, or LED-backlit LCD TVs, are a type of flat-panel television that uses LED (light-emitting diode) technology to illuminate the LCD (liquid crystal display) panel. The LEDs are used as a backlight to illuminate the LCD panel, which displays the image.
An LED TV uses a panel of liquid crystals that are sandwiched between two layers of glass or plastic. The liquid crystals can be manipulated to allow or block light, creating an image. The backlight is made up of a array of LEDs which are positioned behind the LCD panel to illuminate the crystals, creating a bright and vibrant image.
One of the main advantages of LED TVs over traditional LCD TVs is that they use less power and are more energy-efficient. They also have a wider color gamut and can display more vivid and accurate colors. Additionally, LED TVs can be made very thin and lightweight, which makes them ideal for use in portable devices such as smartphones and laptops.
The major disadvantage of LED TVs is that they can be relatively expensive when compared to traditional LCD TVs. However, as the technology continues to improve and costs come down, LED TVs are becoming more affordable and increasingly popular.
Overall, LED TVs are a type of LCD TV that use LED backlighting to produce a brighter and more energy-efficient image. They are widely used in the consumer electronics market and becoming increasingly popular among consumers.
OLED (Organic Light-Emitting Diode)
OLED (Organic Light-Emitting Diode) TVs are a type of flat-panel television that uses OLED technology to create the image. OLED TVs use a thin film of organic compounds that emit light when an electrical current is applied to them. Each pixel in an OLED TV is made up of one or more OLEDs, which can be turned on and off independently to create an image.
One of the main advantages of OLED TVs over other types of flat-panel TVs is their deep black levels and wide viewing angle. OLEDs have a unique ability to turn off completely when displaying black, which creates a true black level and outstanding contrast ratio. Also, OLEDs emit light in all directions, so the image remains consistent and bright even when viewed from off-center angles.
Another advantage of OLED TVs is their ability to produce very fast response times, which means that fast-moving images can be displayed with minimal motion blur. They are also very thin and lightweight, which makes them ideal for use in portable devices such as smartphones and laptops.
A major disadvantage of OLED TVs is that they can be relatively expensive when compared to traditional LCD and LED TVs. Additionally, the organic materials used in OLEDs can degrade over time, which can lead to a decrease in the overall lifespan of the TV.
Overall, OLED TVs are a newer and more advanced technology than LCD or LED TVs. They offer superior image quality, wide viewing angles, and fast response times, but they tend to be more expensive than traditional LCD and LED TVs.
QD-OLED (Quantum Dot-Organic Light Emitting Diode)
QD-OLED (Quantum Dot-Organic Light Emitting Diode) is a type of display technology that combines the benefits of both OLED and quantum dot technology.
In OLED displays, each pixel emits its own light, which allows for very high contrast, deep blacks, and wide viewing angles. But OLEDs are not very energy efficient.
Quantum dots, on the other hand, are tiny semiconductor particles that can emit light in a specific color when excited by a current. They are very energy efficient and can produce a wider color gamut than traditional LCD displays.
QD-OLED combines the strengths of both technologies by using quantum dots as a backlight for the OLED display. The quantum dots enhance the color performance of the OLED display while also increasing its energy efficiency. This technology is still in development and not yet available in consumer products.
QLED vs OLED TV
Imagine a dark night sky, where the stars are the pixels on the screen. QLED TVs would be like having a powerful telescope to view the night sky, where each star is incredibly bright and vibrant, with a wide range of colors. However, the telescope might have a hard time distinguishing the faintest stars, and the image might be washed out if you view it from an angle.
On the other hand, OLED TVs would be like having a pair of binoculars to view the night sky. Each star (pixel) can turn on and off independently, creating deep black levels and outstanding contrast. The binoculars allow you to see even the faintest stars, and the image remains consistent and bright even when viewed from different angles.
QLED TVs can handle bright rooms, high ambient light environments and are great for watching sports or action movies, with high brightness and color accuracy. OLED TVs are ideal for watching movies and TV shows in a dark room, with deep blacks, wide viewing angles, and high contrast ratio.
In summary, QLED TVs offer a powerful telescope-like experience with high brightness and color accuracy, while OLED TVs offer a binocular-like experience with deep blacks, wide viewing angles, and outstanding contrast. Ultimately, it comes down to personal preference, budget, and the type of content you’ll be primarily viewing.
TV’s for gaming
So you want to play on your XBOX, PlayStation, NINTENDO, or PC on your TV, maybe you have a game streaming service?
When it comes to extreme gaming, you want a TV that can keep up with the fast-paced action and provide a smooth, seamless experience. Look for a TV with a high refresh rate, ideally 120Hz or higher, and low input lag. A 4K resolution can also provide a more immersive gaming experience, but make sure your gaming console or PC can handle it.
Additionally, consider a TV with advanced gaming features such as FreeSync or G-Sync, which can help eliminate screen tearing and stuttering. HDR (high dynamic range) can also enhance the color and contrast of your games, making them look more lifelike.
But remember, no matter how great your TV is, it’s not going to make you a better gamer. So, sit back, relax and enjoy the experience!
